LocoNet Throttle

We decided the first EmbeddedLocoNet project should be LocoNet Throttle
Here is a glimpse (thanks to David Harris) of what it will probably look like

The design has the following features: (in likely order of implementation - code space permitting)

• 16x2 LCD Display
• Single or Dual control of two locos or consists with the speed & direction control via either:
  • Two Rotary Encoders for speed control with Fwd/Rev/Stop on the press click action
  • A single rotary POT and SPDT Centre-Off toggle switch for control of a single loco, a bit like a UT1
• A 4x4 keypad for Loco address selection and decoder function operation
• Two LocoNet connectors to allow it to be daisy-chained when the throttle is permanently mounted
• Powered from either:
  • External 9V Wall-Wart for permanently mounted use
  • LocoNet RailSync - may need to add external 12VDC power via a UP3/5 or UR90
  • 9V battery
• Includes 10way header pins for reprogramming the FLASH memory via a simple PC parallel port ISP (In circuit Serial Programmer) programming cable. For details see: Cable Programmer
• Infrared tether-less operation via UR90
• Audible Beeper
• Infrared receiver to decode TV/VCR/DVD IR Remote control signals to provide a remote wireless keypad for when the throttle is permanently mounted

Here are some more generated images of the PCBs
